Expensive phones, why?

Why? Why do you need such an expensive phone? I really do not understand the point. My phone is three years old, smaller than just about any new phone i have seen, and suprise suprise, can call people and text people. I think it might have cost $30 or something with the plan it came with. Great, the phones can play music. Okay, it's shitty quality, holds under 1,000 songs, and chances are if you have such an expensive phone you already have an ipod. They all do the same thing! Unless you are a business man and you need a palm pilot phone, why the fuck do you need to get a new sweet phone every 6 months? It is such a waste of money. Are people so insecure that they need their PHONES to be top of the line to be cool? Okay that was kind of a shitty rant i'll admit, but whatever
